Aswitchworks with thebyte,short,char, andintprimitive data types. It also works withenumerated types(discussed inEnum Types), theStringclass, and a few special classes that wrap certain primitive types:Character,Byte,Short, andInteger(discussed inNumbers and Strings). 1.3 包装类(Wrapper class) By...
the encodings for languages with large character sets have variable length: Some common characters are encoded as single bytes, others require two or more bytes
Having had to use unsigned bytes for the first time, I also had to learn how Java references these datatypes. I did some research, and found a number of good guides out there but was generally dissatisfied with the approach they took to learn the subject matter. Unsigned Data Types Java d...
The seven bits of data in the byte give the value of the character represented. The null character ('\u0000') and characters in the range'\u0080'to'\u07FF'are represented by a pair of bytes x and y: x:110xxxxx y:10yyyyyy The bytes represent the character with the value ((x &0...

一开始是听@Badcode师傅说的这个工具,在Black Hat 2018的一个议题提出来的。这是一个基于字节码静态分析的、利用已知技巧自动查找从source到sink的反序列化利用链工具。看了几遍作者在Black Hat上的演讲视频[1]与PPT[2],想从作者的演讲与PPT中获取更多关于这个工具的原理
